The silicone layer 20 has a function of preventing the composition of the pressure-sensitive adhesive layer 30 and the film layer 40 from being transferred to the release paper 10 and being discolored and denatured.

One end of the pressure-sensitive adhesive layer 30 is bonded to the silicon layer 20, and the other end thereof is laminated with the film layer 40. The pressure-sensitive adhesive layer 30 has a function of attaching the environmentally friendly human body film to a human body part such as a nail or a toenail, and a function of separating the release paper 10 from the function. Here, the pressure-sensitive adhesive layer 30 is preferably, but not limited to, a medical pressure-sensitive adhesive in order to minimize adverse effects of the human body.

The film layer 40 may be prepared by mixing at least one of an alkyd resin, a polyester resin, an acrylic resin, a polyurethane, a urethane resin, a polyamide resin, and / or a vinyl resin with cellulose and / or nitrocellulose, It is preferable to be produced by mixing a resin, at least one of a polyurethane and a urethane resin, and cellulose.

The film layer 40 is formed by coating the coating layer formed of the mixture with 28 to 37% by weight of cellulose, and at least one of the acrylic resin, polyurethane and urethane resin is contained in an amount of 63 to 72% by weight . As a result of various experiments to make the human film of the present invention into a medium-sized film, it was found that cellulose was contained in an amount of 28 to 37% by weight, and the acrylic resin and at least one of the polyurethane and the urethane resin were contained in an amount of 63 to 72% Do. When the composition ratio of cellulose is less than 28% and the composition ratio of acrylic resin, at least one of polyurethane and urethane resin is more than 72%, the human film has soft properties, the printing property in the manufacturing process is poor, If the composition ratio of the cellulose exceeds 37% and the composition ratio of the acrylic resin and at least one of the polyurethane and the urethane resin is less than 63%, the film becomes hard and adheres to the human body part The entire surface area may not be uniformly adhered, or may be broken or broken during manufacture or use.
